What is an equation of the line that passes through the points (4, -1) and (-8, –7)?

Andreas93 [3]

Answer:

y=1/2x-3

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-7-(-1))/(-8-4)

m=(-7+1)/-12

m=-6/-12

m=1/2

y-y1=m(x-x1)

y-(-1)=1/2(x-4)

y+1=1/2x-4/2

y=1/2x-2-1

y=1/2x-3

OR 

YOU CAN USE THE DISTANCE FORMULA AS INDICAYED IN THE PICTURE.
